Tool Permission System
Design and implement a layered, configurable permission/safety system for agent tools. Use this skill when building an agent that needs to control which tool calls are auto-allowed, which require user confirmation, and which are denied — especially when the system must be configurable across multiple scopes (project/user/enterprise) and extensible via hooks. Triggers on: "权限系统", "工具安全", "tool permission", "permission system", "tool safety", "allow/deny rules", "hook system", "构建安全机制".
What this skill does
Tool Permission System is a community-contributed Claude Code skill in the automation sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/tool-permission-system/ and loads when your prompt matches the skill's trigger.
